Our body uses acids and bases everyday to try to get the PH levels as neutral as possible in our bodies. Class 10 Science Lab Manual. Rinse the pH meter. NaOH by their reaction with. A splint was then held over the mouth of the test tubes and the presence of carbon dioxide gas was noted if a popping sound occurred from the calcium carbonate. That is the gas which produced the little bubbles you observed. Unlike the litmus paper, the red cabbage paper gets its color with a little delay. Baking soda and ammonia are basic substances. Some naturally occurring acids are: vinegar acetic acidcitric acid present in orange and lemontartaric acid present in tamarindetc. To measure the acid-basic degree of a substance, you can use pH papers like litmus paper, indicators like phenolphthalein, and electronic pH meters.
